New Advice for Dimming Halogen Lighting

With the current focus on LED lighting, it's easy to forget that millions of halogen lamps are still sold each year in the UK and their use remains widespread. Although halogen lamps are offered at low prices, there is a hidden cost from relatively high failure rates. 

Halogen lamp failures often occur when they are switched on rapidly by a conventional on/off switch but this issue can be overcome by using soft‐start dimmers. Soft-start dimmer switches gently increase the power supplied to a lamp when the dimmer is first turned on, allowing the lamp to warm up gradually, reducing failures caused by stress on halogen lamps when they are switched on. 

So, for the best results with halogen lighting, choose our V-Plus series intelligent dimmers which feature soft-start to regulate the power supplied when the dimmer is first switched on. V-Plus dimmers are suitable for both 1- and 2-way circuits. In a 2-way circuit the dimmer is used in conjunction with a regular switch but the soft‐start feature of the dimmer still regulates the power when the switch is used to turn on the lights. 

For large halogen loads, a new 1000 watt V-Plus dimmer is being added to our range. In white plastic, for example, the part number is IQP1001W. It is recommended that this dimmer is used in place of the HQ9W dimmer for halogen lighting. 

 All our touch and remote control dimmer series feature soft start and so are also suitable for halogen loads in 1-way and 2‐ or multi‐way circuits in conjunction with dimming slaves.

For 1-way circuits our V-Dim series rotary dimmers offer a budget solution for halogen lamps. Similar life‐prolonging benefits are achieved because rotary dimmers switch on at their lowest setting. This, in effect, creates a manual soft‐start for 1‐way circuits and so a new TQR1001W rotary dimmer rated at 1000 watt is being introduced to the V-Dim series.
